“…Orientation of the root crop with the tail part down occurs due to the conical shape of the tail part of the root crop and the moment of gravity arising in the V-shaped groove formed by the combined blades of the rotors, then the root crop is fed through the guide tray 8 into the planting cones of the planting apparatus. According to agritechnical requirements, the speed of planting machines aggregation when planting sugar beet mother plants varies from 1.8 to 3.6 km/h (0.5 ... 1.0 m/s), and the landing step is 0.6 or 0.7 m [8][9].…”

“…At the moment, the task of providing a fully mechanized technological chain from the sampling of sugar beet mother plants to their planting has not been fully resolved. An important role in planting sugar beet mother plants is played by an orienting device, the operation of which largely determines the technological process of single-piece feeding of beet plantings into the planting cones of the planting apparatus, followed by embedding them with a cone downward in the soil and maintaining their original position [4][5][6][7][8].…”

In the total volume of vegetable production, sugar beet takes a leading position. However, the current structure of sugar beet seed production in Russia is not able to meet the needs of agricultural producers with domestic seeds, which leads to a high share of the use of foreign breeding hybrids. Therefore, studies aimed at reducing the cost of manual labor when planting sugar beet mother plants through the development and use of orienting devices for planting machines are relevant. The article presents a three-dimensional model of a rotary paddle orienting device with given design parameters for planting sugar beet mother plants. The power expended on the drive of the rotary paddle orienting device providing the piece-by-piece supply of sugar beet plantings at a planting unit speed of 3.6 km/h has been determined. The kinematic parameters of the operation with the rotary paddle orienting device in conjunction with the landing apparatus of the planting machine have been substantiated. The energy calculation of the drive of the rotary vane orienting device was carried out and the loads acting on it were carried out, as well as the rolling bearings were selected. A chain transmission has been designed and modeled using the KOMPAS 3D computer-aided design system and its main parameters have been determined, which ensure reliable operation of the rotary paddle orienting device.

The mechanization of the technological process in planting sugar beet root crops determines the efficiency of sugar beet seeds production. At the same time, the limiting factor is the use of manual labor in the process of planting sugar beet mother liquors. The article presents a three-dimensional model of an auger orienting device with given design parameters for sowing sugar beet mother liquors. The power for the drive of the auger rollers orienting device is determined, which provides the necessary piece-by-piece supply of sugar beet mother liquors at a speed of the sowing unit of 3.6 km/h. The authors carried out the consistency substantiation of the kinematic parameters in auger orienting device operation with the landing apparatus of the sowing machine, taking into account the design parameters of the presented device. The energy calculation of the auger drive orienting device was carried out and the loads acting on the drive shaft of the roller were determined. The gear wheels of the roller drive have been designed, and the stress-strain analysis of the drive shaft of the auger roller has been carried out. The main parameters of the simulated spur gear were determined using the KOMPAS 3D computer-aided design system, which ensure the reliable operation of the auger orienting device of the machine for planting sugar beet root crops with the required productivity.
